In this study, a method of corrugated width limit alignment processes (CWLA) was applied to pre-twin in hot-rolled Mg alloy sheets. The microstructure evolution and mechanical properties of the CWLA sheets were studied. The results demonstrated that the grain orientation was transformed from strong basal texture to RD-rotated texture after CWLA treatment and up to 22.2% of {10-12} tensile twin boundaries were produced in the microstructure. The 60 ± 5° < 10-10 > twin variant pairs were dominant in the twinned microstructure. Two kinds of dynamic recrystallization (DRX) mechanism, i.e., continuous DRX (CDRX) at low-temperature CWLA and the discontinuous DRX (DDRX) at high-temperature condition were observed. After post-annealing, the twin-induced static recrystallization (SRX) and abnormal grain growth were observed in the CWLA samples, and most twin boundaries were retained. After CAWL for 60 min at 300 °C and post annealing, an improvement on plasticity and strength were achieved with 55% increment for uniform elongation (UE) and 10% increment for ultimate tensile strength (UTS).

“…Conversely, during low speed/load conditions, equipment performance requirements are relatively low, but there are still certain efficiency and reliability requirements for energy absorbing materials. Therefore, the paper conducted experiments under low speed/low load conditions to explore the EA characteristics of materials, providing a basis for further research on the application of high speed/high load environments [9].…”

In the context of environmental protection and energy conservation, it is of great practical significance to study the design of porous material energy absorbing structures on the ground of spider web biomimetic structures. This study designs a porous material energy absorbing structure on the ground of a biomimetic spider web structure. Through in-depth research and experiments, the characteristics of this structure in efficient energy absorption are demonstrated. It has three types of energy absorbing structures: simple design, spiral and composite. The experimental data showed that the simple structure exhibited an energy absorption of 50 mJ under a 5J impact force, with an energy absorption efficiency of 10 mJ/g. At a 20J impact force, the energy absorption reached 200 mJ and the energy absorption efficiency was 40 mJ/g. Under parameter optimization, the cross-sectional diameter of the spiral and the cross-sectional area of the radial significantly affected the energy absorption effect. Reducing the cross-sectional diameter of the spiral from 0.55 mm to 0.45 mm would result in a decrease in energy absorption from 1.775J to 1.59J. When the cross-sectional area of the radial line changed from 0.5 to 0.45, the energy absorption effect decreased from 1.775J to 1.644J. Under static load, the composite structure had a 700 N triggering force and lower peak stress compared to the spiral structure under a compression displacement of 10 mm without compaction. The comprehensive performance of the composite structure is superior. This study provides a reference for designing more efficient and reliable energy absorbing materials, and the results have theoretical significance and practical application value. On the ground of experimental data and conclusions, biomimetic spider web structures can achieve safe, efficient, and reliable energy absorption protection in modern industrial applications, providing important theoretical support and technical guidance. The study of the energy absorption structure of porous materials based on spider web biosimulation has important theoretical and practical value in improving the safety, efficiency, and reliability of modern industrial applications. It provides a new direction and strategy for the development and application of high-performance energy absorption materials.

The effects of Al content on microstructure, texture, and mechanical properties of as-extruded Mg–3Nd alloy were investigated. The particle stimulated nucleation effect of Al2Nd and Al11Nd3 phases promotes dynamic recrystallisation and the texture is weakened of the as-extruded alloys. With the increase in Al content in the alloys, the microstructure transformed from a bimodal structure to an almost fully recrystallised structure. Grain refinement, the distribution of the second phases, and texture are important factors determining the mechanical properties of as-extruded alloys. As-extruded Mg–3Nd–3Al achieved a good balance of strength and plasticity. The ultimate tensile strength, yield strength, and elongation are 283, 221.3 MPa, and 15.7%, respectively.
